Discovery insure thinks it is ok to use Pirate parts on a claim

Very disappointed with the level of service from Discovery insure. In the event of a claim Discovery insure encourages their service providers to use generic parts on your vehicle. Their reasoning is that it saves them money on the claims. I purchased my Audi Q5 new in 2021 and now they expect me to be happy with pirate parts on my vehicle .If I want original Audi parts I need to get a letter from Audi SA stating that pirate parts will void my warranty. Discovery insure makes it sound as if they are doing me a favour by installing the parts my vehicle was originally purchased with. I contacted the claims consultant Bianca Plaatjies to explain how this is fair, but she ignored my email. My vehicle premiums increase every year even though vehicle depreciates I spend over R20k a month on Discovery products , and I think it is time to change.
